the first issue I see that needs to be corrected is that the code for setting the session variables is before the code for the recordset.

the session variables use recordet values, so need to be created after the recordset.

change the code at line 8 - 60:

php:
<?php

if (!session_id()) session_start();
if(!(
$totalRows_rsCoupon == 0))     {
  
$_SESSION["PromoCode"] = "".((isset($_POST["txtPromoCode"]))?$_POST["txtPromoCode"]:"")  ."";
}
?>
<?php
if (!session_id()) session_start();
if(!(
$totalRows_rsCoupon == 0))     {
  
$_SESSION["PromoAmount"] = "".$row_rsCoupon['couponAmount']  ."";
}
?>
<?php

if (!function_exists("GetSQLValueString")) {
function 
GetSQLValueString($theValue$theType$theDefinedValue ""$theNotDefinedValue ""
{
  
$theValue get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  
$theValue function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch (
$theType) {
    case 
"text":
      
$theValue = ($theValue != "") ? "'" $theValue "'" "NULL";
      break;    
    case 
"long":
    case 
"int":
      
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case 
"double":
      
$theValue = ($theValue != "") ? "'" doubleval($theValue) . "'" "NULL";
      break;
    case 
"date":
      
$theValue = ($theValue != "") ? "'" $theValue "'" "NULL";
      break;
    case 
"defined":
      
$theValue = ($theValue != "") ? $theDefinedValue $theNotDefinedValue;
      break;
  }
  return 
$theValue;
}
}

$colname_rsCoupon "-1";
if (isset(
$_POST['txtPromoCode'])) {
  
$colname_rsCoupon = (get_magic_quotes_gpc()) ? $_POST['txtPromoCode'] : addslashes($_POST['txtPromoCode']);
}
mysql_select_db($database_hellolittleone$hellolittleone);
$query_rsCoupon sprintf("SELECT * FROM coupons WHERE couponCode = %s"GetSQLValueString($colname_rsCoupon"text"));
$rsCoupon mysql_query($query_rsCoupon$hellolittleone) or die(mysql_error());
$row_rsCoupon mysql_fetch_assoc($rsCoupon);
$totalRows_rsCoupon mysql_num_rows($rsCoupon);
?>




to:

php:
<?php


if (!function_exists("GetSQLValueString")) {
function 
GetSQLValueString($theValue$theType$theDefinedValue ""$theNotDefinedValue ""
{
  
$theValue get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  
$theValue function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch (
$theType) {
    case 
"text":
      
$theValue = ($theValue != "") ? "'" $theValue "'" "NULL";
      break;    
    case 
"long":
    case 
"int":
      
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case 
"double":
      
$theValue = ($theValue != "") ? "'" doubleval($theValue) . "'" "NULL";
      break;
    case 
"date":
      
$theValue = ($theValue != "") ? "'" $theValue "'" "NULL";
      break;
    case 
"defined":
      
$theValue = ($theValue != "") ? $theDefinedValue $theNotDefinedValue;
      break;
  }
  return 
$theValue;
}
}

$colname_rsCoupon "-1";
if (isset(
$_POST['txtPromoCode'])) {
  
$colname_rsCoupon = (get_magic_quotes_gpc()) ? $_POST['txtPromoCode'] : addslashes($_POST['txtPromoCode']);
}
mysql_select_db($database_hellolittleone$hellolittleone);
$query_rsCoupon sprintf("SELECT * FROM coupons WHERE couponCode = %s"GetSQLValueString($colname_rsCoupon"text"));
$rsCoupon mysql_query($query_rsCoupon$hellolittleone) or die(mysql_error());
$row_rsCoupon mysql_fetch_assoc($rsCoupon);
$totalRows_rsCoupon mysql_num_rows($rsCoupon);
?>
<?php
if (!session_id()) session_start();
if(!(
$totalRows_rsCoupon == 0))     {
  
$_SESSION["PromoCode"] = "".((isset($_POST["txtPromoCode"]))?$_POST["txtPromoCode"]:"")  ."";
}
?>
<?php
if (!session_id()) session_start();
if(!(
$totalRows_rsCoupon == 0))     {
  
$_SESSION["PromoAmount"] = "".$row_rsCoupon['couponAmount']  ."";
}
?>



so the sessions will be created after the recordset.
